ENVELOPE,

@FEGKFICATION forming part of- Letters Patent No. 453,726, dated June 9, 1891.

Application filed February 17, 1890- Berial No. 840,756- (No model-l .To all whom it may concern.-

Be it known that I, HENRY F.- POST, a citizenoi the United States, residing at Paterson, Passaic county, State of New Jersey, have invented a new and useful Improvement in Envelopes, of which the following isa speciiicatiomreferenoe being had to the accompanying drawings, forming a part thereof.

- The object of my present invention is -to facilitate the opcningof envelopes. v I attain the object sought by devices that are illustr'Tate'd in the accompanying drawings, which will be hereinafter fully described and g vclaimed, in which-- ."Figure 1' shows in elevation an envelope embodying my inventiomin which figure the envelope is closed and sealed. Fig. 2 shows the parts of Fig. 1, in which figure-the envelopo is open, with a part of one fold removed; and Fig. 3 is a part view withthe envelope closed, my invention being applied in such figure.

' A represents an envelope of any shape or size, in the interior of which envelope, at one end of the same under the fold B and between said fold and part 0' of the envelope, I arrange and fix a cylindrical severing-wire or opener D. The opener or severing-wire D,

which-possesses s uflicient fineness to present a sharp cutting-surface to the part of the envelope to be cut or severed-,1 secure at one end at e by turning a'portion of the same over and on the fold B, with a slight inward tendency thereon, as shown. In this position the severing-wire D is held fixed 'at e by the' lower edge of the fold B, and is adapted in such position to offer suflicient resistance to admit of the severing. and separating of the parts in the operation of opening the envelope. The opposite hook end of the metallic opener D, I turn over upon the fold B fora considerable distance, and place the same in the position shown, the hook portion being inward, in which position and shape that end of the severing-wire or opener D is adapted to remain indefinitely without being disturbed under the folds C F when the envelope is closed and sealed.

That the position of the operating end of picked up, I carve a thumb-space E in each of the folds C and F of theenvelopeA,which carvings are made to correspond with each other when the envelope is closed, and which are adapted to expose to view that part of. the .opener D at f between the parts h g of the envelope. This cylindrical severing-wire or opener D, which always presents a like cutting surface to the parts of the envelope to be severed and separated in the operatign of opening, is drawn by'the thumb at f from the carvings orthumb-spaces E in an outward and downward direction, which action at f upon the opener-by the thumb i draws the end at g from underthe folds C .F and brings the severer at h into severing contact with the parts to be separated when the same is drawn by the thumb and finger, as in Fig. 3,. until the end of the envelope'is open, when which is withdrawn at pleasure.

' It will be seen that the carvings or spaces E, when taken in connection with the metallic severer D, form onejof the important features of my invention, as they not only exposeto view the position of the severing-'wire, but

done the contents of the envelope may bealso invite and accommodate the action of the end bent double and exposed through the said notches, and with its extreme end hooked and concealed inside the envelope, substantially as and for the purpose set forth.
